BURNER. 7i

Specification of Letters Patent.

Patented July 15, 1919.

Application mea January 2o, 1919. serial iro/272,035.

To all whom t may concern.' y

Be it known that I, WILBUR F. DAY, a citizen of the United States, resident of St. Paul, county of Ramsey, State of Minnesota, have invented certain new and useful Improvements in Burners, of which the following is a specication.

The object of my present invention is to provide a supporting means for the liame deflector which will aid in vaporizing the liquid fuel in the generator.

A further object is to provide improved means for supplying moisture to the burner flame to promote combustion.

A further object is to provide means for directing any overplus of oil entering the retort and dripping through the air ad.-

`mission chamber back to the priming pan.

Other objects of the invention will appear from the following detailed description.

The invention consists generally in various constructions and combinations, all as hereinafter described and particularly pointed out in the claims.

In the accompanying drawings forming part of this specification,

Figure 1 is a side elevation, partially in section, of a burner embodying my invention, l

Fig. 2 is a plan view of the same, also partially in section,

Fig. 3 is a sectional view on the line 8-3 of Fig. 1,

Fig. 4 is a sectional view through the pipe supporting the deflector plate,

Fig. 5 is a plan view ofa modified oonstruction. i

v In the drawing, 2 represents the base of the burner. adapted to be seated on the stove grate within the fire-box, as usual in burners of this type and as particularly shown and described in my U. S. Patent issued'Ma-y 16, 1916, No. 1,181,748. y

The burner shown in Fig. 1 is of'the'double type, with a generating chamber or retort at each end of the base. I will therefore describe the one shown in sectionindicating the corresponding parts of the other retortwith the same reference numerals.

`3 represents a member, preferably tubular in form, comprising an air admission 'chamber of the burner and having recesses 4 in its upper walls to receive the pipe section' 5'of the retort or generator. This retort may be ofl any suitablemetal, shown here Ias east, comprising an outer part 6, substan-J tially oval in form and having a passage 7 therein with the part 5 bridging the opening of the part 6 and integrally joined therewith at the ends. The part 6 is substantially a hollow ring and at a point opposite the passage leading to the part 5 is provided with an opening and a nipple 8 for connection with a coupling 9 in the base, said coupling having a pipe 10 for communication with a source of liquid fuel supply, not shown. r1`he other side of the part 6 adjacent the opposite end of the bridging member 5 is tapped to receive a goose-neck pipe l1 which'eXtends upwardly and has a horizontal part 12 overhanging the burner, the end of the pipe being closed by a suitable cap 13. On this horizontal part 12 a delicotor plate 14 is loosely mounted for adjusting back and forth on the pipe and being positioned over the middle portion of the part 5, and the chamber 3 operates as a deiector for the ame of the burner. The direct passage through the bridging part 5 is closed by a plug 15 and the upper wall ofthis part has a centrally arranged port 16 which forms the nozzle of the burner. Extending around the member 3 is a priming pan 17 in which a quantity of the liquid fuel may be placed and ignited. The walls of the generator will thereby be heated until a surticiently high temperature is obtained to vaporize the oil delivered to the generator and this vapor ignited at the nozzle 16 will supply. the liame for the burner.

As the liquid fuel flows through the pipe 10 and enters the hollow ring-like member 6, it will flow in opposite directions throu h the sections of this member around to t e entrance of the part 5 and then will flow down this part to the nozzle 16. During this flow the fuel will be vaporized and the part 12 of lthe pipe 11 will be heated to a very high degree by the flame of thelburner and the transmission of the heat through the metal and the radiation from the'pipe llwill provide a more intense heat in the generator to assist vaporization. This pipe has therefore two functions. It aids in vaporizing the liquid fuel and also forms a support for the deflector plate. i

,It sometimes happensthat an excess of oil will be delivered to the generator and before it becomes suiiciently hot to vaporize a portion of this oil may escape through the nozzle andmwouldp ordinarily drip, down .through the chamber 3Y into the base of 1rol the stove. To avoid this waste, I provide a bridge 18 extending across from wall to wall of the chamber 3 and curved in'cross section to form a trough, which is preferably inclined, the wall of the chamber having a port ,19 therein communicating with theV discharge end of the trough so that such eX- cess liquid falling into the trough will flow therefrom through the port 19 into the priming chamber.

I also prefer to provide a water chamber 20 on the base of the burner between the chamber 3 with a supply pipe 21 communi eating tlierewithand having a suitable regulating valve (not shown). This pipe 21 may be supplied by gravity or pressure, asprefei'red. By opening the valve a supply of water to the desired depth may be maintained in the water chamber. When the burner is in use, evaporation will take place in this chamber and the air charged with moisture will flow up around 'and into the iiame of the burner and produce a better` combustion and more intense heat.

In Fig. 5 I have shown a modified construction iii which a circular burner 23 is provided, encircled by a circular priming pan 24. rlhe air admission chamber, also preferably circular in form, indicated by reference numeral 3, is encircled by the generator and corresponds substantially in its general construction to the one shown in the previous iigures. This Fig. 5 also illustrates the horizontal pipe section 12 supporting the llame deiiector 14. A water pan 20a, circular in form, encircles the priming pan.

It will be noted that the generator can be easily removed from the burner by merely detacliing the coupling 9 which permits the nipple 8, the generator and the pipe 11 to `be lifted clear of the wall of the air admission chamber.

I have shown the pipe 11 extending lengthwise ofthe burner base along the center linel thereof, but do not confine myself to this position.l as it may be arranged in any other suitable position.
